SRD 'Attack - Shooting or Throwing into a Melee': a target at least 10 ft from the nearest friendly character lets you avoid the -4 penalty entirely (0, not -2). The -2 is reserved for targets two size categories larger than the engaged friendlies (0 at three+), which is not modeled (documented). Golden transcript unaffected (shot still misses).

PF1e (CRB, Measuring Distance): "You can't move diagonally past a corner
(even by taking a 5-foot step)". _best_move_step (the greedy descent behind
the auto-directed move/run/5-foot-step) now enforces the same
diagonal_allowed corner check _step5_to and _best_flee_step already apply.
tests/test_combat.py::test_ranged_no_line_of_effect_moves_around_wall
pinned the old corner-cutting step (0,1)->(1,2) past the wall at (0,2);
re-scripted for the legal (0,1)->(1,1) path (wall cover now applies).

PF1e (CRB Attacks of Opportunity): moving out of more than one square
threatened by the same opponent in the same round counts as one
opportunity for that opponent. Track per-round movement provocation in
_move_aoo_provoked (cleared with _aoo_used at round start); the stand-up
trigger passes movement=False and still provokes. Ranged, casting and
maneuver triggers are untouched.

- New Action kind 'full_attack': manufactured weapons (count=1) gain BAB
iteratives at +6/+11/+16 (-5/-10/-15 from attack bonus, capped at 4);
natural weapons (count>1) delegate to _attack (no iteratives).
- Extracted _resolve_swing from _attack: one swing, log, stats, target-down
check. Both _attack and _full_attack use it. AttackResult gains base_bonus
field so the transcript shows the actual bonus used per iterative.
- default_policy now returns full_attack instead of attack when in range.
Non-breaking for BAB < 6 (single swing, identical transcript).
- Refactored round_no to self._current_round instance variable, removing it
from 6 method signatures and fixing PLR0913 on _resolve_swing.
- 4 new tests: BAB+6 two iteratives, BAB+11 three iteratives, target drops
mid-full-attack, BAB<6 single swing. README and docstring updated; test
count 202 -> 206.
- _flanking_bonus checks for an active same-side ally with a melee weapon
at the position diametrically opposite the attacker through the target.
- +2 applies to melee attack rolls and crit-confirm rolls; ranged attacks
ignore flanking; allies without melee weapons don't threaten.
- AttackResult gains flank_bonus field; transcript shows '+2(flank)' when
active.
- 6 new tests: opposite ally grants +2, no ally = no bonus, ranged ignores
flanking, diagonal flanking, downed ally doesn't flank, enemy on opposite
side doesn't flank.
- README and module docstring updated; test count 196 -> 202.
- default_policy returns (move, attack) when target out of reach: full-speed
move along the Dijkstra path (up to speed cells, 5-10-5 diagonals, stops
adjacent to nearest enemy), then attack if a weapon is usable; returns
(attack,) when already in range.
- _move logs the full path in one line (start)->(step1)->...->(end); silent
on empty path. _execute is silent on invalid attacks/moves (no spurious
wait log); run() adds a wait line only when a combatant's turn produced
no transcript line.
- Extract _take_turn helper from run() to keep cyclomatic complexity <= 10.
- Module docstring updated for activated economy.
- 4 pinned transcripts regenerated (move-then-attack shifts combat pacing):
test_default_policy_moves_toward_enemy, test_scripted_2v2_transcript
(monsters win in R2 instead of R3 — orc-2 moves + attacks same turn),
test_ranged_no_line_of_effect_moves_around_wall (archer rounds wall and
shoots in 1 turn), test_ranged_weapon_unusable_beyond_maximum_range
(archer moves 6 cells then attacks at -14 penalty).
- README: demo numbers refreshed (1v2: 49.6%->22.0%, 11.4->5.2 rounds;
3v2: 97.8%->91.4%, 6.9->6.0 rounds), rules and non-modeled sections
updated for the activated economy.
A weapon with count>1 ('2x Talons') now resolves one independent attack
roll per swing in the same attack action (label '#N'), aggregating stats
per swing. Remaining swings are lost if the target drops mid-routine.
BAB iterative attacks remain out of Phase 0 scope.
Adds the S6 layer on top of the deterministic combat engine:
- metrics.py: closed-form binomial statistics (win rate, standard error,
3-sigma confidence band) with clamped degenerate proportions.
- runner.py: EncounterSpec/Side definitions, per-run SeededRng streams,
global duplicate-id disambiguation, attrition averages per combatant.
- cli.py: pf1e-sim entry point producing a French balance report with
win rates, 3-sigma bands, draws, rounds, and attrition.
- Movement fix: greedy straight-line heuristic could oscillate at walls;
_step_toward now follows the true shortest path via an unbounded
Dijkstra cost field from the target (Grid.reachable budget=None).
- Regression tests: melee unit routes around a wall and engages; grid
unbounded-budget coverage.
